摘　　要：采用多级接触氧化系统对经过物化工艺预处理后的实际汽车涂装废水进行生化处理小试验,考察了溶解氧浓度对多级接触氧化系统整体除碳脱氮效果的影响,并通过正交试验确定了在生化反应器不同位置的溶解氧浓度最优组合。A laboratory experiment has been performed with multilevel bio-contact oxidation system to treat the actual automobile painting wastewater which has been pre-treated by a series of physicochemical processes.The effect of dissolved oxygen concentration on carbon and nitrogen removal efficiency of the multilevel bio-contact oxidation system has been investigated.The orthogonal experiment is employed to optimize the dissolved oxygen concentrations in different locations of the biological reactor,and the optimum dissolved oxygen concentration has been determined.
